Since our last LineageOS post, the project has continued to add new features and support new devices. In addition to new Quick Settings tiles and changes to included apps, the ROM now supports 16 additional devices.

The Galaxy S4, in its day, was a pretty capable smartphone. However, with its fourth birthday fast approaching, its update period has long since passed. No matter to T-Mobile, though; the company has just pushed the latest February 2017 security patches to it and the older Galaxy Tab 3... but they're still on Android 4.4 KitKat.

CyanogenMod's maintainers are on an everlasting quest to conquer the software update war against pesky smartphone manufacturers who drop support way too soon for most of their devices. For instance, Samsung has been struggling to release Marshmallow for the two-year old Galaxy S5, but the CyanogenMod folks are ready to roll Android 6.0's software to an even older flagship: the three-year old Galaxy S4.

In this case, the CM 13 nightlies are available for the AT&T and Sprint versions of the Galaxy S4 (jflteatt and jfltespr respectively). The international S4 got it a couple of months ago, but other carriers and variants are still stuck on CM 11 and CM 12.1.

Samsung isn't leaving its flagship of yesteryear completely high and dry in this age of Stagefright vulnerability. An update is being sent to the Verizon Galaxy S4 today that patches the Stagefright vulnerability, and adds a few more fixes for good measure.

Android Auto is starting to finally show up in cars and third-party head units, but there are still a handful of compatibility issues to work out, it seems. The latest update to the Android Auto app includes compatibility for the Samsung Galaxy S4 and S5 on AT&T, Sprint and Verizon.

So you own a Galaxy S4, Tab 4 8.0 LTE, or Avant and have just received an over-the-air update from T-Mobile. What does it do? Regardless of which of the three devices you own, the answer is the same: not much.

The Galaxy S4, easily the most popular gadget of the three, is receiving a bump to version M919UVUFNK2. This brings with it Chinese language support. Don't speak Chinese? Proceed not to care about this update. The same is true for Avant owners, as the G386TUVU1ANK3 update you're getting hit with sports an identical changelog.
